Release Notes

webdiscus/ansis (ansis)

v4.2.0

Compare Source

• feat: add support named truecolor via ansis.extend().
  Foreground methods are created from the provided color names, and matching background methods bg* are generated automatically.
  Example:

  import ansis from 'ansis';
  import colorNames from 'css-color-names';
  
  const color = ansis.extend(colorNames);
  
  console.log(color.orange('Orange foreground'));
  console.log(color.bgOrange('Orange background')); // auto-generated from "orange"

  This release removes the last barrier for projects migrating from Chalk v4 that used named truecolor, e.g.
  chalk.keyword('orange')('text'). Ansis now provides this feature with a simpler, more intuitive API.

v4.1.0

Compare Source

• feat: add readonly level property to get the detected color support level:
  • 0 - no colors,
  • 1 - 16 colors,
  • 2 - 256 colors,
  • 3 - truecolor.

v4.0.0

Release v4.

Warning: don't update only package.json to major v4, because the new version contains only gray color name.
The very rarely used alias grey was removed as duplicate to keep clean API w/o redundant aliases.

In the src/reporters/fancy.ts file must be changed:

- import { grey } from "ansis";
+ import { gray } from "ansis";

... // TODO: replace "grey" with "gray" in this file

Please, close this PR without merging.
The corrected upgrade PR is #167.
